It turns out, however, that Nicholson didn’t totally love Wahlberg’s improv, and a “little chat” with Scorsese ensued. Check out Wahlberg’s recollection of events below:
“I was improvising throughout the movie and my character obviously didn’t have nice things to say to anybody. So I said some unpleasantries to Jack and he gave me a look that nobody else gave me. And of course, Marty,I did one more and they both had a little chat and then they said, you know, ensure that that’s the end of that.”

Jack Nicholson Brought A Lot Of His Own Ideas
The Departedwas nominated for five Oscars and ended up winning four, including Best Picture and Best Adapted Screenplay. Clearly, William Monahan’s script for the film was airtight, but that doesn’t mean there wasn’t a great deal of improv happening on set. Numerous behind-the-scenes stories fromThe Departed, for example, have become legend, particularly those involving Nicholson’s Costello performance.

Nicholson toldVarietyin 2007 that he improvised parts of a key scene with DiCaprio in which he intimidates and interrogates Billy. According to the actor, he requested that the prop department “hide a gun on the set,” with the weapon not having been written into the script.When Costello pulls the gun out while talking to Billy, there’s real fear on DiCaprio’s face, and it totally changes the dynamic of the scene.
Damon would similarly reveal toFilmInkthat it was Nicholson’s idea to flash a dildo during a scene set in a porn theater. Damon also shared on theWTF With Marc Maronpodcast thatNicholson brought some of his own sinister ideas to a scene inThe Departedin which Costello executes a woman, with the actor pushing to include several lines about how she “fell funny” after he shot her. While Nicholson certainly seems to have done a lot of improvising while filmingThe Departed, Wahlberg’s story suggests playing Dignam meant sticking more to what appears in the script.
